    摘要: The instant invention is a process for the conversion of aliphatic cyclic amines to aliphatic diamines. The process for conversion of aliphatic cyclic amines to aliphatic diamines comprises the steps of: (1) selecting one or more cyclic amines; (2) contacting said one or more cyclic amines with ammonia and hydrogen, optionally water, and optionally one or more solvents in the presence of one or more heterogeneous metal based catalyst systems at a temperature in the range of from 120° C to about 250° C and a pressure in the range of from 700 to 3500 psig for a period in the range of at least one hour or more in one or more reactor systems; (3) forming a product mixture comprising one or more aliphatic diamine, optionally a portion of said one or more cyclic amines, optionally a portion of said ammonia, optionally a portion of said hydrogen, optionally water, and optionally a portion of said one or more solvents; (4) removing said product mixture from the reactor system; (5) removing at least a portion of said portion of ammonia, said portion of hydrogen, or mixture thereof from said product mixture via distillation; (6) removing at least a portion of said portion of water via distillation; (7) removing at least a portion of said portion of one or more optional solvents via distillation; (8) removing at least a portion of said portion of one or more cyclic amines; (9) thereby separating said one or more aliphatic diamines from said product mixture; and (10) thereby converting said one or more cyclic amines to one or more aliphatic diamines.
